If at first you don't succeed... you use the other workable solution. This
following example clearly shows that you can maintain even distribution of
a normal pattern for each object in the csg operation and it looks kool too !

  camera {location<0,0,-5>look_at 0}
  light_source {<0,0,-20> rgb 1}

  #declare Norm = normal { gradient x+y 1 rotate 45*x+y scale .5 frequency 2}

  union {
 sphere { 0, 1 pigment { rgb<1,0,0> } translate<-1, 0,0>normal {Norm} }
 sphere { 0, 1 pigment { rgb<1,1,0> } translate< 1, 0,0>normal {Norm} }
 sphere { 0, 1 pigment { rgb<0,1,0> } translate< 0,-1,0>normal {Norm} }
 sphere { 0, 1 pigment { rgb<0,0,1> } translate< 0, 1,0>normal {Norm} }
        }
